distribute storage domains
by Jason M. Stallings
Hello
I'm trying to figure out a way to automatically distribute our storage
domain occupation evenly or at least avoid them getting full. We have a lot
of users creating vms and they seem to select the first available storage
domain, thus one is nearly full and the rest are barely used.
Is there a way to accomplish that?
Thank you
Jason

port_security in external networks-API
by ada per
Hello everyone,
I have the following python script that creates an external network, but now after updating ovirt a new option "network port security" exists that is set as enabled by default.
How can i disable the network port security?
thanks!! :)
networks_service = connection.system_service().networks_service()
# Use the "add" method to create new VM logical network in data center
network = networks_service.add(
network=types.Network(
name= ext_net_name,
description='Network for testing API',
data_center=types.DataCenter(
name='Default'
),
usages=[types.NetworkUsage.VM],
external_provider=types.OpenStackNetworkProvider(
id=provider.id
)
),

hosted engine installation / multipath / iscsi
by Michael Frank
Hi,
since several days i try to install the hosted engine initially to an iscsi multipath device without success.
Some information on the environment:
- Version 4.3.3
- using two 10gbe interfaces as single bond for the ovirtmgmt interface
- using two 10gbe storage interfaces on each hypervisor for iscsi storage
-- each storage interface is configured without any bonding, etc
-- each storage interface lives in a separate vlan were also the iscsi Portals/target are available, the iscsi portals have 4x10ge interfaces each, (2 in vlan xx and 2 interfaces in vlan yy )
-- so; each storage interface is connected to two iscsi Portals via 4 interfaces
The documentation here is for me unclear:
https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_En...
>Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options.
This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ?
I login to the two iscsi portals and get in sum 8 pathes, 4 from each interface and iscsi target.
Basically I have then the mpath device on the hypervisor available and i can mount the mpath device and put data on it.
In the cockpit interface the mount can also be activated and is recognized correctly.
multipathd -ll and lsblk looks good. Everything seems to be fine.
But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data.
So, basically i just want to define my mpath device - when entering the data (ip, port)for the iscsi Portal I can see the 4 pathes of the single hosted Engine target,
and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have
here for using the multipath device.
I' m lost - what is the usual way to install the HE on a multipath device ?
Do i have to change the configuration of the storage interfaces or the iscsi network design?
Did I missed something obvious ?
Can I put in my multipath data into the answerfile to get rid of the last step of the assistant ?
Can I use the related ansible role for specify the Mpath device which is available when activating the multipath service ?
Is it not possible in general ?? :

Sorry in advance for the long mail .... 1!^^

Re: Linux VM keeps crashing on copying files "with lost communication with qemu"
by Strahil
Maybe the libvirtd < - > libgfapi communication is somehow broken.
I'm using FUSE and I have no issues, but my lab is not I/O intensive .
Have you noticed if the issue happens during I/O (for example - full backup) intensive load?
You can even try to stop using libgfapi and check if it happens again.
Best Regards,

But libvirt seems to have some issues and vdsmd stops being able to poll disk usage. My VMs don’t crash or stop working, but they do report as ? in the management interface and can’t be migrated. Current work around is to restart libvirtd then vdsmd, occasionally restarting libvirtd restarts a VM (presumably the one that had broken some disk something…).

Hello!
The UX Research team at Red Hat is conducting a new oVirt study and is
looking to test out the usability of a few features in oVirt.
We are currently recruiting participants located in the United States and
internationally. If you are interested, please use this calendar to sign up
for a spot:
https://calendar.google.com/calendar/selfsched?sstoken=UUhJcjBDd09oOXg5fG...
The study is open to international participants but getting compensated is
only available to US based participants currently.
For this study, you will be required to use FireFox and allow your screen
and audio to be recorded. This study should only take about 45 minutes to
complete and will be conducted via Bluejeans. All data will be totally
anonymous and viewed only by the UX research team. As a token of our
gratitude, we will be providing you with an Amazon gift card to compensate
you for your time. Your feedback will help us make the project better!
Thank you in advance for your time!
Please let me know if you have any questions.

Data Center Compatibility version
by Rick A
So I updated our environment a bit ago during a scheduled down time from 4.2 to 4.3. Everything went smoothly, but it looks like I forgot to update the Data Center Compatibility (See alert message below). My question is, can I just change the Data Center compatibility to 4.3 while the environment is running without causing issues, or do i need to shutdown all my VM's and put the hosts into maintenance mode? The compatibility version for everything else is already set to 4.3.
Thanks
Alert Message:
"Data Center compatibility version is 4.2, which is lower than latest engine version 4.3. Please upgrade your Data Center to latest version to successfully finish upgrade of your setup"
